Abstract

Relay protection devices in power systems are crucial components ensuring the safe operation of power systems. However, the occurrence of maloperation of relay protection devices not only affects the stability of power systems but may also lead to equipment damage and interruptions in power supply. The causes of maloperation are complex and may be related to equipment failures, system design, environmental factors, or human operations. This paper analyzes the common causes of maloperation of relay protection devices and proposes targeted improvement schemes, including optimizing protection settings, strengthening equipment maintenance, and enhancing operator training. By strengthening research and improvement on maloperation, the reliability of relay protection devices can be effectively improved, ensuring the safe and stable operation of power systems.
